Several days ago，some students from the US visited our school． When we talked，l discov-ered (41) differences in school life between the US and China． For example，each class (42) fifty minutes in the US． It is a little (43)   than that in China． We usually have forty or forty-five minutes iii each class． Another difference is that they have less break time between (44) ．13esides，although most schools in both countries finish their (45) classes at 120 'clock，the students in the US only have an-hour-long break，so they (46) eat lunch quickly． Their af-ternoon classes begin at l:00 pm and school is over (47) 3:00 pm． Then they take part in club activities or play sports．          

Many Chinese students don't work during their high school years ，while the US students．like to find a part-time job in (48) free time． They don't have a dream job in mind． They think   (49) is no difference between jobs． Working is a useful experience for them and they make money at the same time． Some of them even take one-year full time jobs (50 )they leave high school and then go to college．

I have thousands of classes since I started school rune years ago． But only one (51) was the most important．

It happened Iast term just after I had got a (52) result in an exam．l was sad and had lost my confidence．l decided to go to a class which can tell me how to be (53) ．

The speaker walked into the room． But he did not start talking like a teacher． Instead，he held up a twenty yuan note(钞票) !

"Who wants this?"he asked．( 54) 0f'us in the class put up our hands．

He smiled． Then he put up the note on the blackboard and asked the same question． A-gain，we all put up our hands． He smiled again but said (55) ． Suddenly，he threw the note on-to the floor! Then he asked the same question a (56) time．

I didn't understand what the speaker was doing． Why was he asking the same question a-gain and again? I wanted the note，(57) I put my hand up again． After a while，he (58) the note and started to laugh． "You have all just told me how to become successful． "

"The note is worth(价值) 20 yuan．It is (59) worth 20 yuan，even though I threw it on the floor． You are like the note． Whatever happens to you，you still have your worth．

Suddenly I (60) I was worth a lot．l may have done poorly in an exam，but it doesn't mean I can't do well in the future． If I believe in myself，l will be successful!
